This is an oil cooler assembly with a seal set for Volvo TD420VE and TAD420VE engines, designed to dissipate heat from the engine oil, maintaining optimal lubrication and component protection. It is manufactured to meet stringent OEM quality standards, ensuring efficient heat transfer and preventing oil degradation, unlike a clogged or leaking cooler that can lead to increased oil temperatures and wear. Operators may notice elevated oil temperature warnings or a drop in oil pressure if this oil cooler is failing.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Early signs of a failing oil cooler include a gradual increase in engine oil temperature readings or a decrease in oil pressure. If left unaddressed, excessive oil temperatures can lead to accelerated engine wear and potential component seizure. Continued operation risks severe internal engine damage due to inadequate lubrication and overheating.
Thoroughly flush the engine oil passages to remove any debris or contaminants before installing the new oil cooler. Ensure the new seals are properly seated and lubricated to prevent leaks.
Inspect the engine oil filter and oil lines for any signs of blockage or damage when replacing the oil cooler.
